Jonathan Ellis commented on CASSANDRA-2388:
-------------------------------------------
bq. The feasible approach hopefully is still T Jake Luciani's above
Okay. Referring back to Jake's comments,
bq. The biggest problem is [avoiding endpoints in a different DC]. Maybe the
way todo this is change getSplits logic to never return replicas in another DC.
I think this would require adding DC info to the describe_ring call
I note that we expose node snitch location in system.peers. So at worst we
could "join" against that manually.
> ColumnFamilyRecordReader fails for a given split because a host is down, even
> if records could reasonably be read from other replica.
